Appreciate your help and suggestions

Sorry I haven't read word for word your whole post but what is your current vacuum level at warm idle (if you can maintain warm idle)?
Those DW 900's are fairly bulky injectors but shouldn't cause this much issue as they've been used quite often. I'd definitely at least try swapping OEM injectors and changing map to suit just as a test. Easy way to rule it out.
As to vacuum, I'd hook up an external vacuum gauge to a vacuum source just to see what it's coming back with.
As I believe a couple people have stated, leak down etc looks normal for a fresh engine. Have you done any break in what so ever, any moderate loading to bed the rings in? Engine hasn't idled at operating temperature for extended periods of time before rings bedding in? This
could cause low compression etc due to poor ring bedding. Id also try running the engine in on the dyno (moderate load, 50% throttle then 75% throttle) or however your engine builder recommends and check everything again.
